An annual algal diversity of Lakhna, Etawah, Uttar Pradesh, India
The nature of an ecosystem can be easily assumed by the presence of planktonic diversity, as they have a major role in oxygen amelioration, binding and removal of toxic substances from water body. The present enumeration deals with the annual algal diversity from the Lakhna town of Etawah, Uttar Pradesh. During this one year period, total fifty-four species of Algae recorded viz. Achnanthes minutissima, Amphora ovalis, Anabaena oscillarioides, A. oryzae, Ankistrodesmus falcatus, Aphanocapsa littoralis, Aphanothece microscopica, Arthrospira sp., Calothrix gloeocola, Chlorella vulgaris, Chlorococcum humicola, Chroococcus minor, C. minutes, Cladophora glomerata, Closterium venus, Coelosphaerium kuetzingianum, Cyclotella meneghiniana, Cylindrospermum minutissimum, Euglena minuta, Fragilaria crotonensis, Gloeocapsa magma, Gloeotrichia pisum, Gomphonema parvulum, Hydrodictyon reticulatum, Lyngbya contorta, L. epiphytica, L. majuscula, Merismopedia glauca, M. tenuissima, Microcystis aeruginosa, M. flos-aquae, M. robusta, Mougeotia calcarea, Navicula ambigua, N. brebissonii, N. lata, Nostoc commune, N. punctiforme, Oscillatoria formosa, O. subuliformis, O. princeps, Pediastrum boryanum, Phormidium ambiguum, P. fragile, P. lucidum, Rivularia aquatica, Scenedesmus bijuga, S. obliquus, Spirogyra affinis, S. submaxima, Spirulina gigantea, S. major, Ulothrix zonata, Zygnema collinsianum.

Physico Chemical Characteristics of Lakhna Devi Temple Water Tank, Lakhna, Bakewar, Etawah, U.P. with reference to Cyanobacterial Diversity
Fresh water bodies in populated plains of tropical countries face various disturbances in the form of pollutant and nutrient inflow, heavy metal and elemental precipitation (wet or dry) and constant silt inflow (natural or anthropogenic). The physico-chemical characteristics are very much important for any water body. In lentic water bodies these characteristics shows very much variation because in summer they have less and in rains large amount of water. These adverse constrain effectively influence the algal assemblage and can be a good indicator of overall health of the water body. In the study different Physico-chemical characteristics and algal diversity were monthly observed for one year duration (Jun. 2008 to May 2009). Some of 31 species of Cyanobacteria recorded from the study site viz. Microcystis aerughinosa, M. flos-aquae, M. robusta, Chroococcus minor, C.minutes, Gloeocapsa magma, Aphanocapsa littoralis, Aphanothece microscopis, Coelosphaerium kuetzingianum, Merismopedia glauca, M. tenuissima, Arthrospira spriulinoides, Spirulina gigantean, S. major, Oscillatoria formosa, O. subuliformis, O. princeps, Phormidium ambiguum, P. fragile, P. lucidum, Lyngbya contorta, O. epiphytica, O.majuscule, Cylindrospermum minutissimum, Nostoc commune, N. punctiforme, Anabaena oscillarioides, A. oryzae, Calothrix gloeocola, Rivularia aquatic and Gloeotrichia pisum
Tree species of the Himalayan Terai region of Uttar Pradesh, India: a checklist
The study catalogues a sum of 278 tree species belonging to 185 genera and 57 families from the Terai region of Uttar Pradesh. The family Fabaceae has been found to exhibit the highest generic and species diversity with 23 genera and 44 species. The genus Ficus of Moraceae has been observed the largest with 15 species. About 50% species exhibit deciduous nature in the forest. Out of total species occurring in the region, about 63% are native to India. Almost all tree species have some importance in one and another way for the local people. In the study area about 80 species flower in the spring, 74 in the summer, 73 in the winter and 30 in rainy season. As per the existing IUCN Red List, 24 species of the area fall under different categories. Presence of these red listed trees in the study area enhances the importance of their proper management and conservation plan
Isolated Ficus trees deliver dual conservation and development benefits in a rural landscape
Abstract Many of the world's rural populations are dependent on the local provision of economically and medicinally important plant resources. However, increasing land-use intensity is depleting these resources, reducing human welfare, and thereby constraining development. Here we investigate a low cost strategy to manage the availability of valuable plant resources, facilitated by the use of isolated Ficus trees as restoration nuclei. We surveyed the plants growing under 207 isolated trees in Assam, India, and categorized them according to their local human-uses. We found that Ficus trees were associated with double the density of important high-grade timber, firewood, human food, livestock fodder, and medicinal plants compared to non-Ficus trees. Management practices were also important in determining the density of valuable plants, with grazing pressure and land-use intensity significantly affecting densities in most categories. Community management practices that conserve isolated Ficus trees, and restrict livestock grazing and high-intensity land-use in their vicinity, can promote plant growth and the provision of important local resources
Synopsis of the genus Ficus L. (Moraceae) in India
A checklist of all species of Ficus L. available in the present political boundary of India is provided. About 115 taxa (89 species and 26 infraspecific taxa) of Ficus have been recorded here based on all available information. The taxa have been arranged according to the current classification among six subgenera and 12 sections. The maximum number of the species belongs to subgenera Urostigma. For each species, correct nomenclature with first citation followed by several relevant works and important synonyms has been provided along with Indian as well as world distribution. The taxonomic comments have also been provided for many species, if found necessary. Out of the 115 taxa occurring in India, only 10 taxa have been recorded as endemic. One new combination Ficus hirta Vahl subsp. triloba (Buch.-Ham. ex Voigt) Chaudhary has been proposed. In India, the species are distributed throughout the country from South to North up to the Himalayas at about 2,000 m elevations. The maximum diversity of the species lies in the North-East region followed by the Peninsular region and Andaman and Nicobar Islands. The province like Meghalaya in the North-East region has very rich diversity of Ficus as far as the number of species is concerned
Lichen as Bioindicator for Monitoring Environmental Status in Western Himalaya, India
The use of bioindicator communities (lichen) to assess the environmental status of an area is a well-proved strategy to monitor any habitat without any logistic and instrumental facilities. In the present study, 13 bioindicator communities of lichen have been used to assess the environmental status of holy pilgrimage (Badrinath), western Himalaya, India. Three sites (i.e. Badrinath, Mana & pilgrimage route from Bhimpul to Vasudhara) have been comparatively assessed. The results of the study reveals that Badrinath site is less polluted and experiences low degree of anthropogenic disturbances compared to Mana, and pilgrimage route (Bhimpul to Vasudhara). Human settlements, construction of civil works, vehicular emission, and trampling and trekking by tourists are the major threats on these habitats, which ultimately decrease the quality of vegetation and adjacent environment. Controlled vehicular use, promotion of modern way of cooking and managed trekking in these pilgrimage routes could be helpful to combat the decreasing vegetation and environmental quality therein.INTERNATIONAL JOURNAL OF ENVIRONMENTVolume-5, Issue-2, Mar-May 2016 page: 1-15</p
